How to Ping a Network for Testing Connectivity
Ping! If you listen closely, that’s the sound of the ping command at work. A ping network test transmits data packets to a specific IP address and either confirms or denies there is connectivity between IP-networked devices.
In the case of confirmation, you will discover the “latency” (i.e., the length of the response time) by performing a ping test. A lower latency provides a better experience, as even milliseconds can matter in situations, like online gaming, where a fast response is essential.
If the ping fails, this can point to the need for further investigation to locate the root cause. So, how does pinging a network work?
What is ping exactly?
Users can send a ping command through a Windows, Mac, or Linux computer. It’s a helpful utility that’s been around since the early 80’s. The term comes from sonar technology, which sends out a sound wave and then listens for a ping (or echoes) in return. The longer the interval, the farther away an object must be.
The same principle applies to networks as data requests route around the globe. Pinging can also call out network congestion or other latency problems, such as a server being down. Running a ping test is fairly straightforward.
How to run a ping network test
The steps to executing a ping network test depend upon the operating system you’re using.
For Windows 10, go to Search in the taskbar and:
- Type “cmd” to bring up the Command Prompt.
- Open the Command Prompt.
- Type “ping” in the black box and hit the space bar.
- Type the IP address you’d like to ping (e.g., 192.XXX.X.X).
- Review the ping results displayed.
For Macs, follow the same cadence by opening Network Utility and inputting the hostname or IP address you’d like to ping.
For Linux, open Terminal. You can also use the traceroute command to review the different IP addresses your request routes through. To do this, simply:
- Open Terminal.
- Type “traceroute” followed by the IP address or URL you wish to trace.
- Hit Enter and review the results.
What are some common addresses to ping?
When performing your ping tests, you might do so by simply checking your own internet connectivity. To accomplish this, you want to ensure that the IP address you’re pinging is indeed up and functioning.
While every address could experience downtime at some point, some dependable choices for you to ping include:
- 220.127.116.11 and 18.104.22.168 (OpenDNS)
- 22.214.171.124 and 126.96.36.199 (Cloudflare)
- 188.8.131.52 and 184.108.40.206 (Google DNS)
If you don’t receive a response when running a ping test for connectivity for these IP addresses, this likely means there is a problem on your end.
What are other uses for ping?
Aside from performing the occasional ping test, you can also run ping continuously to maintain a constant influx of information. In Linux, the ping application runs until the user chooses to stop the process. To do this, hit CTRL and C simultaneously. The command is the same in Windows. And to keep ping going endlessly in that OS, type “ping -t” in the Command Prompt. Anything else…? Yes, there is.
If you’re looking for more complete pinging capabilities than are natively found in most operating systems, many third-party tools exist to chart and visualize your ping results. These can be helpful for creating quarterly reports for stakeholders.
